我最近很喜欢的一句话（已经忘了出处）：我知道我可以做到，只不过要多花一点时间。
现在每当我开始怀疑自己的时候，都会拿出这句话来提醒自己：多点耐心，你可以的。
在这个时代，“耐心”真的是一个很宝贵的品质。《士兵突击》里，袁朗第二次和许三多见面，彼时钢七连已经解散，许三多一个人守着空无一人的营地宿舍大半年，每天仍然按照正常作息出操。袁朗对许三多说：“我喜欢你，不太焦虑。耐得住寂寞，有很多人天天都在焦虑，怕没得到，怕寂寞，我喜欢不焦虑的人” 。

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”
